Ukip's general election candidate for Clacton has vowed to fight Douglas Carswell for the party's nomination in the upcoming by-election.
Roger Lord said he would "absolutely" fight for the nomination. "I have been assured I will get a fair hearing," he told Radio 4's Today programme.
Asked whether he would step aside to make way for Mr Carswell, Mr Lord replied, "We are not a party that stands down. We don't bend, we don't break. We fight."
Mr Lord also accused Mr Carswell of jumping ship from the Conservatives because the water was "around his ankles".
